    SD-4 Generator Interlock Kit
    this kit fits brands:
    Square D
    type of circuit breaker panel:
    1 handle vertical throw up and down main breaker centered over 2 breaker columns with a 3 to 3 1/2 inch space between main breaker and column breakers
    panel spaces used:
    2 at the top of the right side breaker column
    National Electrical Code requires a system in place that prevents an emergency generator from feeding back into the utility line. This interlock will only allow the generator breaker to be switched on if the main breaker is off. Or the main breaker to be turned on if the generator breaker is off.
    You will also need:
    A generator with a 240 volt outlet
    A double breaker located at the top of the right side breaker column of your electrical panel box
    An inlet box and wiring connected to that double breaker
    Using this interlock will allow you to power your existing house wiring with your generator (within its wattage limits), including 220 volt circuits such as a well pump.  This interlock is not listed. It does meet the requirements of Article 702 of the National Electrical Code ANSI/NFPA 70.
